The AirTAC GFR60020F2 AirTAC Filter Regulator PT3/4, 40 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020F2 is a 600-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded PT3/4, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl purges as the pressure differential across the element builds. The fitted embedded square gauge reads in psi, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, optional 5 um filtration (code W), automatic or manual drain alternatives, gauge scales in MPa, psi or bar, an optional external round gauge, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Clean, regulated air feeding the tool-clamp and chip-clearing cylinders on a CNC machining centre, with the 40 um element stopping scale and pipe debris from reaching the clamping valves.
Conditioned air for the stop-and-divert cylinders on a bottling conveyor, where the differential-pressure drain keeps condensate out of the diverters without an operator opening a drain valve each shift.
Point-of-use filtration and pressure setting at 3/4 inch air drops in an assembly plant, letting each station dial in its own downstream pressure on the psi gauge independent of the main header.
Size the unit by stepping through the 200/300/400/600 range against the port your air line already uses - here that is 3/4 inch on PT thread, with G (BSPP) and NPT available to order. Choose the drain to match how the unit is serviced: differential-pressure (this model) purges on pressure differential, automatic drains hands-free, and manual drain suits attended installations. The standard 40 um element protects most actuators and valves; specify the 5 um W grade where finer protection matters. Gauge scale (MPa, psi or bar) and the embedded square versus optional external round gauge are your call, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm the datasheet curves and sizing before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as performance curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application - line pressure, downstream demand and allowable pressure drop - and we will confirm the datasheet curves and check the sizing with you before you order.
With a blank drain position, the GFR60020F2 drains the bowl by differential pressure: condensate is expelled as the pressure drop across the 40 um element builds, with no operator input. If you prefer hands-free purging regardless of differential, or a manual drain valve for attended installations, the automatic (A) and manual (M) drain versions are available in the same series - ask us to quote the alternative code.
